Il disegno a pastello in Italia nel XVI secolo: un problema critico

Il tema della ricerca sono i caratteri della grafica a pastello in area italiana nel XVI secolo. Il lavoro è articolato in tre parti. Il primo capitolo analizza l’uso e il significato del termine “pastello” nelle fonti Cinque-Seicentesche. Il secondo capitolo ricostruisce il dibattito critico multidisciplinare sull’argomento. Se da una parte l’attenzione riservata al pastello da specialisti di diversi settori ha portato a una feconda varietà di punti di vista, dall’altro ha avuto come risultato una serie di ricostruzioni frammentarie. All’interno del dibattito sulla tecnica è stato possibile distinguere posizioni differenziate, in parte conseguenza dei diversi approcci e specializzazioni, ed enucleare alcuni nodi critici meritevoli di approfondimento. In primo luogo è possibile distinguere varie opinioni sulla fondamentale questione della natura e dei criteri di identificazione del medium, in particolare per i disegni risalenti al XVI secolo ovvero alla fase “embrionale” dell’utilizzo della tecnica. Si è proceduto poi, sulla base di queste premesse, all’analisi dei disegni del XVI secolo tradizionalmente ritenuti o recentemente proposti dalla storiografia come opere a pastello in ambito milanese, nelle aree settentrionali e centro-italiane. Successivamente è stato quindi studiato il ruolo della tecnica all’interno della grafica di Federico Barocci e Jacopo Bassano , i due artisti che si dedicano con maggiore intensità all’esplorazione delle possibilità del medium. Sono state infine considerate opere di artisti appartenenti alle generazioni successive (sempre entro il XVI secolo) che sperimentano l’uso dei pastelli policromi sul modello di Barocci e Bassano.

Racismo e decadência: sociedade, cultura e intelectuais em São Luís do Maranhão

O argumento desta tese é que a lenta configuração social do racismo na província do Maranhão pode ser observada como uma consequência inesperada da combinação de três processos distintos entre si, dotados de causalidades e efeitos próprios, mas cujo amálgama histórico impulsou a valorização simbólica e política das classificações de cor como critério de distinção e controle social. Em primeiro lugar, o processo econômico de derrocada do setor de exportação, diretamente vinculado à plantation escravista em relação à produção voltada para o mercado interno. Em segundo lugar, o crescimento demográfico da população livre de cor no conjunto dos trabalhadores, grupo que se tornou majoritário ainda na primeira metade do século dezenove. Por fim, o lugar periférico do Estado do Maranhão na política brasileira desde o processo de independência. Para demonstrar esta tese analiso a combinação desses processos na cidade de São Luís do Maranhão e os impasses da integração da população negra nessa sociedade que se imaginou como uma Atenas brasileira.

The fashionable horse : Ute saddlebags and saddle blankets 1870-1925

This research paper examines the creation, design, and functions of ten Ute double saddlebags and four beaded Ute saddle blankets fabricated between 1870 and 1925. Based on this sample and comparison with additional Basin and Plains tribal dressings, it appears that Ute saddlebags and blankets possess a combination of characteristics that reflect Ute territory, lifestyle, and aesthetics. These attributes, including fabrication from hide; similar rectangular dimensions; simple geometric beadwork patterns that emphasize triangles; preference for blue, white, and yellow beads; largely solid colored backgrounds; and back entries into the bags, work together to create a style that is specifically Ute.

Portable 3D laser-camera calibration system with color fusion for SLAM

Nowadays, the use of RGB-D sensors have focused a lot of research in computer vision and robotics. These kinds of sensors, like Kinect, allow to obtain 3D data together with color information. However, their working range is limited to less than 10 meters, making them useless in some robotics applications, like outdoor mapping. In these environments, 3D lasers, working in ranges of 20-80 meters, are better. But 3D lasers do not usually provide color information. A simple 2D camera can be used to provide color information to the point cloud, but a calibration process between camera and laser must be done. In this paper we present a portable calibration system to calibrate any traditional camera with a 3D laser in order to assign color information to the 3D points obtained. Thus, we can use laser precision and simultaneously make use of color information. Unlike other techniques that make use of a three-dimensional body of known dimensions in the calibration process, this system is highly portable because it makes use of small catadioptrics that can be placed in a simple manner in the environment. We use our calibration system in a 3D mapping system, including Simultaneous Location and Mapping (SLAM), in order to get a 3D colored map which can be used in different tasks. We show that an additional problem arises: 2D cameras information is different when lighting conditions change. So when we merge 3D point clouds from two different views, several points in a given neighborhood could have different color information. A new method for color fusion is presented, obtaining correct colored maps. The system will be tested by applying it to 3D reconstruction.

Letter from Thomas Hollis to the Curators of Harvard College, 1762 July 21

Thomas Hollis V (1720-1774), widely known as Thomas Hollis of Lincoln’s Inn, was a very generous donor to Harvard College, particularly its library. This letter, which appears to have accompanied a package, demonstrates that he also donated prints to the College. Hollis wrote: "N.B. the Ludlow, Sydney, Marvell, & Cleopatra are struck on paper made from white & colored silk rags, the produce of premiums of the Society, the noble Society for promoting arts & commerce."
